BICYCLE OR TOURIST LOCK.

SPECIFICATION forming part of Letters Patent No. 596,237, dated December28, 1897- Application filed February 15, 1897. Serial No. 623,461. (Nomodel.)

To all whom it may concern.-

Be it known that I, OSCAR DAMON, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Locks, of which thefollowing is a specification.

This invention relates to locks and latches, and particularly to a lockfor bicycles, baggage, and other portable articles to lock the sameagainst removal or transportation, such lock being as readily adaptablefor use as a pad or hasp lock; and the object of the invention is toprovide a new and improved lock of special construction and arrangementof parts.

A further object of the invention is to provide a peculiar and novelmeans for locking the separable parts of the lock together.

The invention consists in the novel construction and arrangement ofparts, and resides, essentially, in the telescoping members or parts andmeans for locking them together.

In the accompanying drawings, forming part of this application, Figure 1is an elevation of the lock with the members in telescopic positionlocked together. Fig. 2' is a longitudinal sectional View with themembers unlocked. Fig. 3 is an enlarged sectional view on the line a;00, Fig. 2, showing the key in position to unlock the members. Fig. 4 isan edge view of Fig. 1. Fig. 5 shows a modified screw projection. Fig. 6is amodified key.

The same numeral references denote the same parts throughout the severalfigures of the drawings.

The lock members consist of a bar or rod 1, forming the shackle,preferably U-shaped, having upon one end teeth 2 and a likeshaped tubeor hollow sleeve 3 to receive the ends of the bar or shackle 1 intelescopic position. The other end of the bar 1 has a longitudinalgroove 4, terminating in an L-shaped groove 5, which engages a lug 6 onthe inside of one end of the tube or sleeve 3, so that the shackle maybe operated to slide in or out of the sleeve the whole length of thesaid groove 4 with the toothed end of the shackle in or out of thesleeve without separating the shackle from the sleeve, said shacklebeing turned to have the lug 6 engage the L-shaped groove 5 to put thetoothed end of the shackle out of the line with the sleeve or toseparate the sleeve entirely. The other end of the sleeve 3 has integralflanges 7, between which is confined a toothed plate 8, adapted to bemoved transversely to the sleeve 3 and provided with a screw-threadedprojection 16.

The plate 8 is controlled by a plate-spring 10,

provided with an aperture 10 having its bearing upon the plate 8 anduponthe top or cover 11, having an aperture 11, and which may be securedupon the flanges 7 to the end pieces 12 in any suitable manner. Theseflanges 7 and the endpieces 12 form the easing for the movablelocking-plate 8 and spring 10,saicl ends 12 having upon the insidetongues 13, engaged bya groove 14 in the endsof the plate 8 and notches15 in the ends of the spring to keep these parts against displacementand to insure the spring and plate against tilting or any frictionalcontact that would impair the free operation of the same. The plate 8 isprovided with a screw-threaded projection 16. The screw-threaded end ofthe key 18 has a collar or shoulder 19, adapted to engage the top orcover 11 when the key is screwed through the apertures 10 and 11 on theprojection 16, and by a continued turn of the key the plate is raisedout of engagement with the teeth of the shackle, which unlocks thelatter from the sleeve 3. It is obvious that immediately upon removingthe key the spring 10 will force the locking-plate 8 back to the sleeveuntil the teeth of the plate project into the sleeve in the path of theshackle.

A chain 20 may be slipped over the shackle and a like chain may also beapplied to the sleeve for the purpose of locking articles to it asdesired, which cannot be reached by the shackle. It will be observedthat the shackle may be extended far into the sleeve or it may beextended far from the sleeve, yet in either position it is locked to thesleeve by pressure of the spring upon the toothed plate.

Referring to Figs. 5 and 6, amodified form of screw projection and keyis shown. The projection has a central opening 21 or is hollow with asquare thread 22, having notches 23 upon opposite sides to admit theprongs 24 of the key 25, while the central projection 26 of the keyenters the opening 21 to insure the proper centering of the key. Theoperation of this form of key and screw projection is the same as thathereinbefore described.

It will be readily seen that the application of my lock is unlimited,and I therefore do not wish to confine myself to its adaptation, nor toany particular size, shape, or manner of making; but,

Having thus described my invention, what i I claim as new, and desire tosecure by Letters Patent, is-

1. A look comprising a sleeve open at its ends, a toothed locking-plateslidably contained in one of the said ends, and a shackle the ends ofwhich are adapted to enter the sleeve ends, one of said shackle endshaving teeth to mesh with the said plate-teeth, as set forth.

2. A lock comprising a sleeve open at its ends, a toothed platecontained in one of said ends, a spring engaging the plate, and ashackle one end of which is revolubly held in the other end of thesleeve, and the other shackle end having teeth to mesh with the saidplate-teeth, as set forth.

3. A look comprising a sleeve, a toothed plate slidably contained in oneend of the sleeve, a lug or projection upon the inside of the other endof the sleeve, and a shackle having teeth upon one end to mesh with theplate-teeth, and the other end having an L- shaped groove engaged bysaid lug or projection, as set forth.

4:. In alock the combination with the sleeve, a casing upon one end ofthe sleeve, and a spring-controlled toothed plate in the casing, of ashackle having teeth upon one end to mesh with said plate-teeth, theother end of the shackle being slidably and revolubly held in the otherend of the sleeve, as set forth.

5. In a lock, the combination with the sleeve having flanges formed uponone end, a top or cover on the flanges, and a shackle having teeth uponone end, of a plate slidably contained between said flanges and havingteeth adapted to enter the sleeve in the path of the shackle-teeth, anda spring between the said top and the toothed plate, as set forth.

' 6. In a lock, the combination with the shackle, the sleeve, and theplate in the sleeve, having a hollow screw projection, of a key havingan exterior collar a central projection to fit the inside of the saidscrew projection and prongs to engage the screw-thread of saidprojection, as set forth.

In witness whereof I hereunto set my hand in the presence of twowitnesses.

OSCAR DAMON.
